Hermet Park ed01ef717e api: revise the spec 
Remove the requirement for unique_ptr in the function prototypes.
This change will simplify the API usage, making it more streamlined
and user-friendly. However, memory management will now be the
responsibility of the user.

C++ API Modification:
- Result Paint::mask(std::unique_ptr<Paint> target, MaskMethod method) -> Result Paint::mask(Paint* target, MaskMethod method)
- Result Paint::clip(std::unique_ptr<Paint> clipper) -> Result Paint::clip(Paint* clipper)
- virtual Result Canvas::push(std::unique_ptr<Paint> paint) -> virtual Result Canvas::push(Paint* paint)
- std::unique_ptr<LinearGradient> LinearGradient::gen() -> LinearGradient* LinearGradient::gen()
- std::unique_ptr<RadialGradient> RadialGradient::gen() -> RadialGradient* RadialGradient::gen()
- Result Shape::strokeFill(std::unique_ptr<Fill> f) -> Result Shape::strokeFill(Fill* f)
- Result Shape::fill(std::unique_ptr<Fill> f) -> Result Shape::fill(Fill* f)
- std::unique_ptr<Shape> Shape::gen() -> Shape* Shape::gen()
- std::unique_ptr<Picture> Picture::gen() -> Result Picture::push(Paint* paint)
- std::unique_ptr<Scene> Scene::gen() -> Scene* Scene::gen()
- Result Text::fill(std::unique_ptr<Fill> f) -> Result Text::fill(Fill* f)
- std::unique_ptr<Text> Text::gen() -> Text* Text::gen()
- std::unique_ptr<SwCanvas> SwCanvas::gen() -> SwCanvas* SwCanvas::gen()
- std::unique_ptr<GlCanvas> GlCanvas::gen() -> GlCanvas* GlCanvas::gen()
- std::unique_ptr<Animation> Animation::gen() -> Animation* Animation::gen()
- Result Saver::background(std::unique_ptr<Paint> paint) -> Result Saver::background(Paint* paint)
- Result Saver::save(std::unique_ptr<Paint> paint, const char* filename, uint32_t quality = 100) -> Result Saver::save(Paint* paint, const char* filename, uint32_t quality = 100)
- std::unique_ptr<Saver> Saver::gen() -> Saver* Saver::gen()
- std::unique_ptr<Accessor> Accessor::gen() -> Accessor* Accessor::gen()

C++ API removal:
- template<typename T = tvg::Paint> std::unique_ptr<T> cast(Paint* paint)
- template<typename T = tvg::Paint> std::unique_ptr<T> cast(Paint* paint)
